! WARNING

Failure to monitor the condition of all parts and take 

corrective action as necessary may lead to failure during 

use resulting in personal injury or property damage.

Check all output string bolts along the drive train 

periodically to ensure they remain tight. Loose or damaged 

bolts may fail at, or below the anchor’s torque rating or 

contribute to damage elsewhere in the output string. Check 

all parts periodically for wear or damage and replace as 

necessary. Replacement bolts must be the same grade and 

length as the originals.

These instructions are intended to illustrate the use of the Helical Pole Support. Anchor installing tools covered

in this instruction sheet should be used by competent personnel familiar with and following good work and safety

practices. Should additional information and details be desired, or if speciﬁc situations arise which are not covered

adequately for the user’s purpose the speciﬁcs should be referred to Hubbell Power Systems (HPS). In some cases,

HPS may make speciﬁc recommendations concerning installation torque and installed depth limits for speciﬁc

applications.

NOTE: The Locking Dog Assembly has three positions. The inside

ring position allows the locking dogs to hold both the drive end

assembly and the anchor rod. The middle position releases the

anchor rod but holds the wrench drive end assembly. The outside

position releases the Drive-End Assembly

RECOMMENDED TIGHTENING TORQUES

BOLT DRY TORQUE (ft.-lb.)

1/2" - Gr. 5 75

5/8" - Gr. 2 95

1/2" - Set Screw 15 to 20

3. Before installing the Drive End Assembly in the

Locking Dog Assembly, open the dogs by pulling

outward and twisting in a counterclockwise direction

until the release rings rest on the outside stops.

1. Slide Kelly bar into the socket on the Kelly Bar

Adapter. Holes in the two opposite walls of the socket

allow the kelly bar shaft to be pinned in place with

the bent-arm pin provided. Coil locks are provided

and must be used to keep the bent arm pin from slip-

ping out. These pins should be checked periodically

and replaced with original equipment as necessary to

avoid failure.

2. When mounting the Locking Dog Assembly directly

in a Chance Kelly Bar Adapter (both having clear-

ance holes) use the 1/2-inch diameter grade 5 bolts,

or the 5/8-inch diameter grade 2 bolts, nuts, and

lockwashers provided with the Locking Dog Assembly

or those provided with the Kelly Bar Adapter. When

mounting the Locking Dog Assembly to a Chance

Kelly Bar Adapter (having tapped holes), the 1/2-

inch diameter grade 5, or the 5/8-inch diameter grade

2 bolts provided with the Kelly Bar Adapter must be

used. Those provided with the Locking Dog Assembly

will not work.

4. With the release rings

in the outside position,

insert the Drive End

Assembly into the

Locking Dog Assembly.

Rotate rings to the inside

position to capture drive

end in the Locking Dog

Assembly.

5. Assemble the lead section,

extension, and Helical

Pole Support together.

Place the anchor assembly

into the center of the hole.

6. Insert the Drive End

Assembly into the Helical

Pole Support.

! CAUTION

Dangerous stored energy can cause severe injury or death.

Relieve installation torque from output string before 

removing the wrench.

7. Begin driving the anchor assembly into the ground.

Maintain down pressure during installation to

ensure tool engagement.

10. Continue installing until Helical Pole Support

reaches the bottom of the hole. Remove the Drive

End Assembly and set the pole according standard

practices.

9. Torque can be monitored during installation.

8. If additional anchor length is required, stop

installing when the Helical Pole Support coupling is

at grade. Remove Helical Pole Support and add an

extension. Then bolt Helical Pole Support back to

the extension and continue driving. Repeat this step

until desired depth is reached..

These instructions do not claim to cover all details or variations in equipment, nor to provide for all  possible conditions to be 

met with concerning installation, operation, or maintenance of this equipment. If further information is desired or if particular 

problems are encountered which are not sufﬁciently covered in this guide, contact Hubbell Power Systems.
